Definitions

  • the invention concerns a process for shaping a sheet or thin tubular piece of plastic or multi-layered metal-plastic material, particularly in the domain of packaging.
  • multi-layered metal-plastic material is used to refer to a material, the parallel layers of which consist of at least one inner layer of metal, e.g., of aluminum, and two surface layers of a plastic material.
  • Applicant has investigated whether it is possible to produce well controlled incised engravings on tubular pieces of plastic material without creating distortions, and, if possible, while avoiding the constraints of a heating operation.
  • the invention relates to a process for producing markings or lines engraved on a sheet or a tubular piece made of plastic material or multi-layered metal-plastic material less than 1 mm in thickness, typically between 0.25 and 0.8 mm, in which the sheet or piece is gripped between a tool bearing one or more marking reliefs (6) and a resilient supporting means for the purpose of producing the engraved markings or lines.
  • the sheet or piece is at less than 70° C. and preferably at less than 50° C. during the gripping stage, and the resilient supporting means has a Shore hardness D of between 70 and 120, the engraved markings or lines being produced by plastic deformation with elastic return.
  • the hollows are obtained without a heating operation, or, as a matter of convenience, on a luke-warm product, this being preferable to a heating operation for mass production and to improve the reproducibility of the results.
  • the marking is effected by slightly exceeding the elastic limit of the gripped plastic material.
  • the choice of resilient supporting means is particularly important in order to produce engraved markings which are controlled and reproducible.
  • the supporting means according to the invention is much harder than the relatively soft elastomeric supporting means according to U.S. Pat. No. 4,130,623, the hardness A of which is between 35 and 60, equivalent to a Shore hardness D of between 7 and 16.
  • the resilient supporting means is responsible for improving, by compression, the distribution of the elongations when the deformations are made for the purpose of producing engraved markings on the sheet or piece, and, concurrently, to avoid local flattening and thinning which would impair the mechanical resistance and impermeability of the marked layer.
  • An engraved deformation is thus produced without unacceptable distortion of the non-heated plastic material, which is thus rather rigid, whereas the prior art uses a heated state in which the material is much more deformable and even soft.
  • the hardness of the supporting means is too great, flexing or twisting may occur.
  • there is a high degree of compression in the bottom of the hollows i.e., between the end of the marked contours and the supporting means which is too hard, but the sheet or marked piece penetrates into this supporting means to only a small extent, so that its lateral sides are not supported.
  • flexing can be observed on the sheet or tube which corresponds to the main orientation of the marking contours.
  • the sheet or piece prefferably at a temperature of at least 15° C. when it is being marked during the gripping stage.
  • a lower temperature causes a reduction in the ductility which can affect the capacity of the sheet or piece to be susceptible to engraved deformation.
  • Polyolefins are particularly suited to this kind of engraved marking.
  • the Shore hardness D of the supporting means is preferably between 85 and 110.
  • the Shore hardness D of the supporting means is preferably between 100 and 120.
  • the resilient supporting means is preferably made of a material selected from the group consisting of polyurethane, natural or/synthetic rubber, silicones, and charged silicones.
  • the supporting means is preferably in the form of an insert supported and flanged by a rigid piece, a steel piece, for example.
  • the insert is then preferably pressed quite close to the engraved deformations which it must contain and control; in practice it is between 1 and 5 mm wider than the useful width of the marking outlines.
  • an insert of this kind for marking outlines with a useful height, or penetration height, of between 0.2 and 0.6 mm, so as to produce engraved markings or lines which are between 0.05 mm and 0.2 mm in depth.
  • the tubular piece is first marked with two laminated longitudinal folds before inserting the engraved markings or lines, the folds having at the top before inserting the engraved markings or lines, the folds having at the top thereof an outer striction hollow, i.e., a reduction in section resulting from extension of a test plate, which is between 2% and 15% the thickness of the piece in depth, the folds then being elastically hinged.
  • the marking process according to the invention is used in the manufacture of flexible tubes, a tubular piece forming the blank of the flexible skirt of the tube, and the blank being marked with engravings after having possibly been provided with longitudinal folds prior to fixing, typically by molding, the plastic head of the tube onto one end of the blank.
  • tubular blanks which are between 0.2 and 0.6 mm in thickness
  • the top layer to be marked being at least 0.2 mm in thickness in the case of a multi-layered blank, so as not to impair the barrier layer.
  • the invention permits simple renewal at ambient temperature, at all events at less than 70° C., of the surface appearance and state of thin treated pieces, in particular the skirts of flexible tubes. Decorations of engraved markings or lines are obtained without recourse being made to impression; they thus permit improved gripping, the marking appearing as corrugations with rounded peaks.
  • the combination of engraved markings or liens and longitudinal folds marked by a fine outer stricture produces tubes of improved dimensional stability and of a particular geometry, some of their facets having an engraved decoration or gripping means.
  • engraved marking can be done on an already decorated surface, without destroying it.
  • FIG. 1 shows a longitudinal section of a tube in the course of being marked.
  • FIG. 2 shows a side view of the tube after it has been marked circularly.
  • FIG. 4 shows a longitudinally marked tube, FIG. 3 showing the arrangement of the markings of such tube.
  • FIG. 5 shows a side view of a third flexible tube which has markings in sinuous hollows.
  • FIG. 6 shows a side view of a fourth tube which is marked with a narrow embossed roller with cylindrical circumference.
  • FIG. 7 shows the arrangement for marking of the second and third tube, a longitudinal section of the tube being shown which is in the course of being marked.
  • FIG. 8 shows a perspective view of a fifth tube which has longitudinal folds and portions marked in hollows portions.
  • FIG. 9 shows a cross-section of one of the afore-mentioned creases in unfolded position.
  • FIG. 1 shows a rotatable embossed steel roller 1 which has intersecting contours 2 called “diamond points" 3, these small pyramidal points 3 being 0.4 mm in height.
  • the embossed roller 1 is flanged by two circular cylindrical base surfaces 4 which are coaxial with the roller, the surfaces 4 resting against the tube 6 during the marking operation.
  • the tube 6 is made of high density polyethylene and is 40 mm in diameter and 0.5 mm thick, and has been predecorated in black. It is rotated about its axis 7 a temperature of between 18° and 23° C., thus being gripped between the rotating embossed roller 1 and a fixed counter-support 8 formed by an insert 9 embedded in a rigid support 10 with which is is flush or beyond which it projects less than 0.2 mm. Three sets of tests have been carried out relating to insert 9.
  • a PU insert 9 according to the invention with a Shore hardness of 90 and with the same marking arrangement, was then tested.
  • the tubes 6 obtained had hollows 12 which were quite regular and only 0.1 mm, each annular zone 11 being slightly swollen to a diameter of 40.5 mm. In section, it can be seen that the local deformations of the wall of the tubes are regular, the thickness being between 0.45 and 0.5 mm. Moreover, in the preceding case, there is no impairment to the black decoration.
  • a third test was carried out with a steel insert 9, also outside the invention. Tubes 6 were obtained which were marked with grooves, and which had hollowed out bottoms 12 which were thinned to 0.3 mm in local thickness. Marking of a semi-circumference of the tube resulted in pronounced flexing.
  • the tube 20 which was also made of high density polyethylene and which was 40 x the thickness 0.5 mm in diameter, was entrained longitudinally between the embossed roller 1 and the insert 9 embedded in a fixed rigid support 10, gripping of the embossed roller producing, as before, re-entry of the "diamond points" 3 into the tube 20 or useful height of contours 3 of 4 mm.
  • the PU insert 9 with Shore hardness of 90 gives a zone which is marked with rectilinear edges, without the tubes 20 being offset from their axes, and with an enveloping surface which has a low local excess thickness (0.2 mm).
  • FIGS. 5 and 6 show tubes 30 and 40 which were previously decorated in black and which had an initial diameter of 40 mm ⁇ an initial thickness of 0.5 mm.
  • the tubes were engraved by using a narrow metal embossed roller 31 with a circular cylindrical circumference 33 with a width of 1.2 mm, with a countersupport in the form of a PU inset 9 with a Shore hardness D equal to 90, 4 mm in width, embedded and centered relative to the support end or circumference 33 of the embossed roller 31 (FIG. 7).
  • the tube 30 or 40 had a temperature of between 20° and 30° and was rotated on itself, while its wall was clamped between the embossed roller 31 and the insert 9 which produced on the tube 30 or 40 an engraved groove 32 which was 1 mm in width and 0.15 mm in depth at the diameter.
  • the bottom 34 of the groove was flattened and thinned to 0.45 mm in thickness.
  • the grooves 32 of the rubes 30 or 40 are perfectly regular and in no way impair the black surface.
  • the tube 30 was then sealed at the bottom end.
  • the sinuous groove 32 was obtained by superposing displacements along the tube during the marking operation and by rotating it.
  • the tube 40 has four grooves 32 which are spaced 10 mm apart. It has no overall flexing and the bottoms of the grooves 32 are all slightly less than 39.85 mm in diameter.
  • FIG. 8 shows a tube 62 which has a skirt 50 decorated on the outside in green, 0.5 mm in thickness and made of high density polyethylene, the oppositely disposed folds 61 and 52 and then 53 and 4 having been produced by two successive rolling operations at ambient temperature, the second of these operations flatly gripping the blank which is angularly offset relative to the first rolling operation.
  • the rolls were 0.95 mm apart, i.e., 1.9 times the thickness of the blank.
  • a fine white hollow line was noted at the location of each fold.
  • a study in section of a straight section of the unfolded blank 50 reveals that each white line is an outer striction surface such as 57 in FIG. 9, with a depth between 0.25 and 0.03 mm.
  • An unevenness 58 is also noted inside the fold which is produced by the folding operation with compression. It has been shown that hundreds of folding operations of such a sample present no risk in practice.
  • each small face such as 59, which was 5 mm in width was passed, at ambient temperature, between a rotating embossed roller with oblique needle-shaped outlines with longitudinal pitch of 1 mm and an embedded PU insert of Shore hardness 90, the contours projecting by 0.3 mm and the gripping being such that the bottom surface of the embossed roller bore against the face 59.
  • alternating skimming contours 60 and hollows 61 were produced which where 0.07 mm in depth, forming a milled region 59 which improves gripping of the tube and which has a decorative worth, while the folds 51 to 54 improve elastic stability of the tube, i.e., return to its initial shape after pressing.
  • the folds 51 to 54 and the engraved marking of the small faces 59 were made on the blank of the skirt 50 prior to the head 49 being molded to produce a flexible tube 62.
  • the process for engraved marking according to the invention is used, in particular, in the manufacture of flexible tubes for the cosmetics and pharmaceuticals industries, in hygiene, for the food industry and for repair and maintenance products.
  • the process also makes it possible for the blind to indentify contents from the contours of the tubes.
